Be it known that l, WIxrintn S. ])t'.\'.\, a citizen ol'the United Statcs 'osiding atthe city of Washington, in the District ot Columbia, have invented certain new and uset'nl linprovemcnts in Carriage-Curtaiu .lrastcnings; and I do declare the following to be a full, clear, and exact description 01 the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which t'orin apart of this specification.

This invt-ntioh relates to that class of carriage-curtain fastenings in which the fastening device is attached directly to the curtain and locks with a suitable holdmg device secured upon any part of the carriage to which it is desired to temporarily connect the a-nrtain. Nearly all the fastcnings now in use reverse this method of attachnunit, the stud, button, or other iii-stoning device being at tached to the carriage and conruzcting with the curtain tlnsough the agency of a buttonhole, eyelet, or other properlyconstructed receptacle formed in the curtain. This methtul of construction is, however, open to a serious objection, as the projecting studs upon the seat-arms, bows ot' the top, and other parts are veryliable to catch and tear the clothing of occupants, and, further, do not prevent unauthorized persons t'roni disconnecting the curtains and boot'fastenings, thus exposing the cushions and interior ofthe carriage to the weather. To obviate these objections the object of my invention, by which the fastening device is so const-rjuetcd that it may be attached directly to the curtain or boot, and the catch or keeper with which it conuectsu'pon the carriage embedded in the wood, sons to desired to attach the curtain to a bow or other part which would be weakened by embedding the keeper therein, it is so rounded upon its outer surface and hollowed out upon its inner as to fit closely to the part to which it is sooured and present nothingoutwardly upon which clothing might catch or the hands he with; and, further, instead of providing the fastening with aprojeeting stud or similar device for operating the same,it isso constructed to adapt it to be operated only by a wholly dated February 22, 1 32? set-nu XII). 222,310. (No ino'lvl.)

' disengaged key, no part of thconnecting mcchanisin projecting outside ot the case containing it, and which case is secured to the curtain or bootot' the carriage, Lnus preventing any derangement of the-parts hy unanth0rized parties, as they c: .1 onlybe connected or disconnected by the use of the key which operates the locking-bolt; and the invention consists in the construction and arrangement oi the several parts,by which theyaro adapted to be operated by a key, and present no dan gerous projection, as will be hereiinifter fully described, and specifically pointed out in the claims.

In the accompanying drawings in which similar letters indicate like parts in the different iigurcs, Figure 11. is a pers 'iectivc view of the fastening device attached to a curtain. Fig. 2 shows a bottom plan with the spring and locking-boltin place within the case. Fig.

3 shows the inner side of the case before the ends are bent downto secure thespring. Fig. 4 is a longitiulinal section through the case, spring, curtain, and keeper, with which the lockingsholt is connected. longitudinalsection showing the fastening disvconnected from the keeper. Fig. 6 is a plan view of the under side of the keeper, Fig. 7 is a similar view of the keeper with the lockingboit; attached. Fig. 8 is a perspective view ot' the locking-bolt upon an enlarged scale. Fig. i) isa. transverse section through the fastener and keeper connected, the lat being adapted to be secured to a carriage bow. Fig. 10 is a longitudinal section of the same, with the fastener disconnected; and Fig. it t shows a form of keeper adapted for attach ment to a curtain or other thin flexible part. i

In constructing this .iastcning, I form the case A of metal, presenting outwardly a con VOX surface with a corresponding concavity upon its inner side. In this concavity is placed the curved plate-spring B, held in place by turning down the lips c a upon-its ends Fig. 5 is a similar" after it has been placed in the case. A circular orifice, I), is formed in the case, and a similar one, I), but of less diameter than that in. the case,is for med in the spring I3. Through these orifices passes the lock-bolt G, which is provided with a fixed collar or flange, d, near its outer end, resting upon the outer or convex side oh the spring 15. The locking-bolt proj cots sufticientlybeyond the ilangc d to receive thelooso collar (2. having arooves c in its pcriphery, which, when in the proper position, register with the notches 0, formed in the pcriphery of the flange. A key, D, having a bifurcated end, as shown in Fig. 4,is employed to turnthe locking-bolt, its bifurcations being made to fit the grooves in the collar and the notches in the flange.

The object of the loose collar upon the locking-bolt is to prevent said bolt from being turned except by a properly-constructed key, as when an attempt is made to turn the bolt by other means the collar will turn upon the bolt and cover the notches in the flange which receive the key by which the bolt is operated.

It will be observed that the orifice b in the case is of sufficient diameter to receive the collar and flange of the looking-bolt, so that it may not only turn easily therein, but may also have a slight longitudinal movement when pressed upon by the key, but that the orifice b in the spring is smaller, allowing only the body of the bolt to pass through it, so that when the bolt is pressed by the key it do presses the spring; but when the'pressnre of the key is removed the spring returns the bolt to its normal position, with the outer side of the loose collar oven with the outer surfaceof the case.

E represents the curtain, boot, or other arlicle, to which the case A is secured by means ofrivets or screws ii. An orifice, b, is made through the material of which the part E is composed, and allows the passage through the same of the shaft of the locking-bolt 0. Securely attached to the inner end of this looking-bolt is the cross-bar I1, forming the device by means of which said bolt is connected to the keeper F. This keeper, when it is to be attached to fiat surfaces, is preferably formed with a plane outer surface, and is sunk into the part so as to present no projection therefrom, as shown in Figs. 4'and 5 of the drawings; but when itis to be attached toarounded surface or to a flexible article it may be constructed as shown in Figs. 9 and 11, in the first of which figures it is illustrated with a convex outer and concave inner surface, and is intended for attachment to a carriage-bow, while in Fig. 11 it is shown with a flat inner and rounded outer surface to fit it for attachment to a piece of leather or other thin material, to which it is secured by screws or rivets i.

The form of the under side of the keeper F, with which the locking-bolt engages, is illustratcd by Figs. (5 and 7, L being the elongated 'orifice through which the locking-bolt and crossbar pass, and m a recess in which the cross-bar of the bolt moves when said bolt is turned.

it represents a cross-groove or depression, into which the cross-bar is drawn by the spring B when the bolt has been turned through onequarter of a circle and the cross-bar brought to a position at right angles with the slot k. This groove it holds the cross-bar of the lockingbolt in this locked position until it is forced out of said groove by the application of the key D to the-opposite end of the bolt and sufficient pressure applied to depress the spring B, thus allowing the bolt to move endwise until the cross-bar is out of the groove, when the bolt 'may be turned until the crossbar is in line with the slot k and the ten sion of the spring draws it into said slot, allowing the case A, with the part to which it is attached,to be disconnected from the keeper.

It will be apparent that the special form of key herein shown and described may be departed from without changing the scope of my invention, as other forms might be devised which would accomplish the result-as, forinstance, a narrow groove might be formed in the end of the lockingbolt to receive the thin blade of the key, and other forms might be devised; but prefer that shown as affording the best protection with simplicity of construction.

It will be obviousthatthe peculiar construction of this fastening, partaking of the nature of a lock,wil1 adapt it to other uses than. those of confining the curtains or boot of a carriage. I do not, therefore, confine myself to its use for that purpose solely.

Having thus described my invcntionJclaim as new and desire to secure by Letters Patent the following:

1. As an improvement in carriagecurtain fastenings, the combination of the case A, at tached to the curtains, the spring-plate within said. case, and locking-bolt D, provided with a loose collar, (2, and adapted to be operated by a' disengageable key, for the purpose of locking and unlocking the fastening, as set forth.

2. As an improvement in carriage-curtain fastenings, the combination of the case having a rounded outer surface, inclosing-spring,locking-holt provided with a loose collar, and adapted, as shown and described, to be operated by a key, and a keeper with which said lockingbolt engages,substantially as set forth.

3. As an improvement in carriage-curtain fastenings, the case A and spring B, secured in said case by turning down the lips 11 a, in combination with the locking-bolt 0, provided with flanges d and loose collar (1, having grooves and notches in their peripheries to receive the bifurcated ends of key D, substantially as shown and described.

4. In a curtain-fastener, the case A andlocking-bolt 0, provided with flanges d and collar (2, adapted to be opcrated'by key D, in combination with the curtain E, and keeper F,attached to the carriage, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
